in a position to bring about the change at. any time by one simpleinovement of a lever while composing.

The invention is particularly applicable to line-casting machines of thelinotype system, as for example described in the United States patentspecifications 436,531, 436,532

and 557,000. In these machines the moldwheel is enerally rotated aquarter-revolution between the ejection of one line and the casting ofthe next, the utilized mold being brought into the casting position fromthe ejection position. After a line has been cast,

the mold-wheel is rotated three-quarters of a revolution more, wherebythe mold and the cast line are brought into the ejection position, inorder to deliver the line into the line assembling galley.

Now according to this invention, instead of the mold-wheel rotating thestandard quarter-revolution it is rotated a different amount, whenanother mold is to be used instead of that used previously. Thismodified rotation of the mold-wheel may be a quarter-revolution in theopposite direction. It will be readily understood that, in this event,instead of the utilized mold located in the ejection position anotherone, which is diametrically opposite to the previouslyused mold, arrivesinto the casting position. The invention may, however, be modified by ahalf-revolution or any other fraction of a whole revolution of themoldwheel taking lution backward before. a

this case itis necessary for changing the mold that the wheel rotate aquarter-revm -line is cast, in order to bring the other mold into thecasting position, instead of that mold opposite to it, which has beenpreviously utilized and which would be brought into the casting positiona quarter-revolution forward. Foranoving the mold-wheel backward its'drlving mechanism must be reversed by the main shaft with the aid ofreversing gear. The reversal must be done away with after the firstquarter-revolution of the wheel, while this is stationary for thepurpose of -casting,.in order that the following threequarter revolutionmay take place in the customary direction, 0. forward, and that the moldjust utilized carrying the cast line may arrive into the ejectionposition and into the casting position again before the nextcastingoperation. A fresh. reversal of the reversing gear causes a secondchange of mold to take place. Thus repeated reversal brings about asfrequent a change of mold.

I The devices serving for reversing the direction of rotation of themold-wheel must be constructed having regard to various points. Forexample, the composer can utilize capital letters of large font when hehas to set a line serving as title. In this event he will change thefont at the beginning of the line. In another case, when one single wordto be emphasized occurs in a line, the comooser will only learn of thenecessity of cianging the mold when he begins to set up this word andwill then, make the change. IVhen he returns to the ordinary type afterending such a word, the change which has been prepared may not benegatived. Further, the peculiarities of the casting apparatus in themachine have tobe'taken into consideration. \Vhen the composer begins aline, the previous line will be, as a'rule, in the casting apparatus andthe latter is in operation, and during this timethe driving gear of themold-wheel may not be reversed. Again, the composer may have finishedsetting a line of matrices before the casting apparatus has deliveredthe cast of the previous line; if the composer now begins a new linewith a change of mold, this change may only bc'inade. when the previousline has been completely cast.

-all the cams serving for controlling the casting apparatus. W'ith thebevel wheel 12 is connected a rectangular member 17 (Figs. 3 and 6)which lies against the side face of the wheel 15 and brings about andmaintains the'exact adjustment of the gear wheels 12, 10, +1 and 9 andthe mold-wheel 1. In the normal position of the main shaft the firsttooth of the segment 13 meshes with the wheel 12 and as soon as thecasting apparatus begins to operate drives the wheels 12 and 10 half arevolution. This movement causes the pinion 9, shaft 8 and wheel 4 torotate one complete revolution and the mold-wheel 1 aquarter-revolution, the latter in the direction of the arrow 6 in Fig.7.

In the new mechanism two gear wheels v 10 and 18 are on the shaft 11carrying the bevel wheel 12 and two corresponding pinions 9 and 19 areprovided on the shaft 8.

As in the known arrangement the gears 10 and 9 are in direct engagement,but the gears 18 and 19, on the contrary, are connected with one anotherby an intermediate wheel 20. The latter imparts the rotation of thetoothed wheel 18 to the pinion 19, so that this rotates simultaneouslywith, but ina direction opposite to, the pinion 9. The latter is notfirmly connected with the shaft 8 as in the known arrangenenubut by adetachable clutch, as clearly shown in Fig. 6. The pinion 19 isconnected in like manner by a clutch with the, shaft end, the twopinions 9 and 19 have incisions 23 and 21, respectively, in their hubs21' and 22, respectively. Driving pins 25 and 26, secured in the rod 27,can be introduced into these incisions by means of a rod 27 movablelongitudinally in the hollow shaft 8? The distance between the pins and26 is so much greater than the distance between the hubs 21 and 22 thatthe pins can only engage alternately in the hubs of the wheels.

Behind the pin 26 is a ring 30 loose on the shaft 8 and a powerfulspring 31 which acts on the pins 25 and 26 and the rod 27. The springabuts against a ring 32 secured on the shaft 8 and tends to place thepin 26 into the slot 2403f the hub 22 and simultaneously to remove thepin 25 out of the slot 23 in the hub 21. The pinions 9 and 19 areprevented from moving longitudinally alongthe shaft 8. The rod 27projects beyond the end of the shaft 8 and has here a spherical face 35which lies in a spherical face 3 of a lever 37, as clearly shown in Fig.5. This lever is rigidly connected with an axle 38 and thereby with thelever 39 secured 611' the same axle. The lever 39 has To this i a roller40 at its to end and an extension 11. This abuts agamst'the arm 13(Figs. 3 and 5) of an angle lever which can rock around the pivot 4e andhas an arm extending vertically upward. A draw rod 46 is pivoted at 17to the arm i5 and at 18 to a two-armed lever 49, 50. This lever isfulcrumed on the pivot 51 and can reciprocate with thispivot secured ina lever 52 which rotates with the shaft 53 and the arm 54. The bottomend of the lever is located above the rear end of the shaft 56 carryingat its front end the lever 76 (Figs. 1 and 3) which serves for throwinginto gear the casting apparatus and for controlling theline-transferring*earriage 77, it being connected with the latter by arod 76*. WVhen the assembling elevator E of the machine rises theline-transferring carriage 77 is liberated inknown manner fromacatch 80and then moves under the influence of a spring 78, which is attached tothe lever arm 7 9 secured on the shaft 56, with the set line'to thefirst elevator H (Fig. l). The lever arm 57 carrying the roller 58participates in the'rotation of the shaft 56 which takes place. Theroller finally arrives in its extreme position against aclickpwherebythe latter is released and. causes the main clutch of thecasting apparatus to be engaged. This and the other occurrences in thecasting apparatus are not material for the mechanism which is to bedescribed.

On the bushing 59, by means of which the lever 57 is secured on theshaft 56, is a pro-- jection or lug 60 which is located approxi-"m'ately vertically under the bottom end of the lever 50. -The positionof the lug is selected such thatvthe line connecting its front facewith'the center of the shaft in the normal position forms approximatelyan eng n of 45 with the vertical and that itappro'ximately coincideswith the vertical wheathrhaft 56 has rotated out of its normal positioninto its extreme position f r'actuatin'g the driving clutch of themachine. It wil beg'readily understood that the pointpf the l ilgmoves,during this rotation, along an arc and that this movementca'n e resolvedinto a norizontal and a vertical component. The two components of themovement are utilized in various ways in the apparatus.

As long as no change of mold is to take placethe bottom end of the lever50 is at such an elevation that the lug 60 does not contact with thelever arm 50 during a rotation of the shaft 56. This elevation ismaintained by a locking device which coacts with the lever arm 54, andthe arm 52 and the lever 49, 50 are thereby prevented from descending.This locking device com.- prises a locking lever 62 fulcrumed on theaxle 63 and pivotally connected to a rod 65. This connecting-rod 65' isconnected by the cation the roller 69 is pressed downward by theprojection 72 of the se ment 71. Each reciprocation of the ban le 73causes a change of mold, the described apparatus working as follows:When the roller '69 is pressed downward the rod and the looking lever 62are lifted. The latter slides off the end of the arm 54 and releases thesame. Owing to the weight of the lever 49, 50 the arm 52 carrying thislever rocks around the shaft 53 and drives the arm 54. When the roller69 has passed the projection 72 on segment 71. it returns into itsnormal position, the'locking lever 62 remaining on the broad end of thearm 54. The rod 65, being guided by the pivot 64 in an oval slot andthereby independently of the looking lever 62 falls immediately backinto its bottom position and by its excess weight presses the roller 69againstthe segment 71 thus preventing an accidental movement of thelatter. When the arm 54 is released, the lever 49, 50 moves downwardlylongitudinally and its bottom end arrives in front of the lug 60. Duringthe subsequent movement of the. line-transferring carriage, namely whena line is next conveyed from the setting to the casting position, thelug drives the bottom end of the lever 49, '50 and moves this laterallyfrom left to right and, in addition, the entire lever 49, 50 upward.Owing to the latter movement, which is due to lug 60, the lever arms 52and 54 are returned into their normal positions; the locking lever 62again falls in front of the lever arm 54 and holds the same until it isreleased afresh, and the bottom end of the lever 49, 50 is out of reachof thelug 60 as soon as this has returned into its normal position.Simultaneously with the upward movement, however, a lateral movement ofthe lever arm 50 occurs, the same rocking around the pivot 51. Thislateral movement is transmitted in the opposite direction by the arm 49and the draw-rod 46 to the angle lever 43,45 rocking around the pivot44. In

consequence of this movement the arm 43 releases the extension 41 of thelever arm 39, and the lever 37 connected with the latter now moves underthe action of the rod 27 in .the shaft 8 and the spring 31 influencingarrive by means of a three-quarter revolution in the direction of thearrow 6 into the ejection position after the cast is finished. To thisend, the rod 27 having the two driving pins 25 and 26 mustbe returnedinto its original position directly after the completion of the firstuarter-revolution of the mold wheel. This is brought about by means ofacam 75 which is provided on the .main shaft 16 and coacts with theroller 40 on the lever arm 39. While the mold-wheel itself is at rest onaccount of the casting, the main shaft 16 rotates and the cam 75 returnsthe roller 40, the levers 39 and 37 and the pins 25, 26 into theiroriginal, normal positions. The driving gear of the moldwheel is therebyreversed afresh so that the wheel rotates again in theordinarydirection. At the beginning of the subsequent casting operation the mold3 is in the ejection position and owing to the ordinary rotation of thewheel 1 arrives into the casting position 5. The mold 3 remains in useuntil the mold 2 arrives again into the casting position 5 owing to anew temporary reversal of the rotation of the mold-wheel.

It follows from the above that the change of mold takes place, ifoccasioned by means of the handle 73, when the line in question isconveyed from the setting to the casting position. If a line be situatedbetween the setting and casting positions, in the socalled waitingposition the shaft56 and the lug 60 have turned so far that the bottomend of the lever 49, 50, when released in this moment does not fall infront of the lug 60 but onto the back thereof. Consequently, the end ofthe lever arm 50 is not driven when the transferring of said line isgoing on but remains in the disengaged position until the lug 60 returnsinto its normal position, which can only occur when the linetransferringcarriage has delivered the line situated in the waiting position to thefirst or casting elevator.

The 'cam75 is formed in such manner that it only admits of the reversalof the driving device when the casting apparatus is located in theejection position or in the rest position. In each intermediate positionthe cam 75 coacts with the roller 40 and thereby prevents reversal until,the casting operation is finished. I

Mechanism for adjusting the line trimming blades has to be combined withthe and is of varying height according in each instance to the width ofthe mold.

In Figs. 9 and 10 the mold is illustrated in cross-section in twodifferent positions opposite the blades. Of the two blades or cutters100 and 101 the former is stationary whereas the latter is arranged torock around an axle 102.- This axle is journaled in an adjustable holder103 secured by means of screws 104 to the body 106. The latter isconnected by means of screwbol ts 107 with the frame 108 of thematrix-clamping device commonly called the vise. The holder 103 can beso adjusted by means of an attachment screw 109 and two adjustmentscrews 110 (Figs. 8 and 9) that the edge 111 of the blade 101 isparallel with the edge 112' of the blade'100. The blade 101 is notconnected directly with the axle 102 but with a support or carrier 113secured on the axle 102. On this support is an abutment or arm 11 1which enters into the incision 96 in the mold soon as the mold isopposite the blades and is caused to approach the latter by the machine.Further, a body 115 having two arms 116 and 117 is journaled on the axle102; these arms enter into the movable abutments or pins 118 and 119,respectively, which move in guiding bushes 120 and 121, respectively.These guides or bushes 120 and 121 are slotted at 122 (Fig. 9).Likewise, the pins 118 and 119 have slots into which the lever arms 116and 117 respectively enter. Further, there are connected with .the body115 which carries the lever arms 116 and 117 two additional lever arms125 and 126, against which the ends of a leaf spring 127 press andthereby tend to rotate the bodv 115 carrying said arms so that the pins118 and 11.9 are shifted forward as far as possible. Two

faces 131, one of which is provided on each of the arms 116 and 117(Fig. 9) now drive the body carrying the blade 101 by means of the faces129 provided on this body 0pposite to the faces 131 (l igs. 8, 9 and 10)so far that the edge 111 of the blade 101 is removed as far possiblefrom the edge 112 of the blade 100. The arm rigidly connected orintegral with .the'body 113 also participates in this rotation. If themoldwheel 1 carrying the mold 2 is now caused to approach the blades,which is brought about automatically by the machine before the ejectionof the line in well-known manner, two stops or abutments 133, .Which areintegral or rigidly connected with the mold, opposite to the pins 118and 119, press on these pins and thereby rock the levers 116, 117,115around the axle'102 against the action of the leaf spring 127. Thespring 134 tends to impart the rotation of the body 115 to the body 113and the blade 101, and the body 113 yields to this force until the lever11 1 abuts against the face 98 of the mold 2. At this moment the correctdistance between thsa-edges 111 and 112 of the blades is obtained. Thefurther rotation of the body 115 only compresses the spring 134 therebysecuring the position of the blade 101'. The ejector 135 now begins topush the cast line 136 out of the mold 2 and conveys it between theedges 111 and 112 into the galley 137 in front of the blades (Fig. 1).After the mold has receded the leaf spring 127 returns the body 115having the arms 116 and 117 and the pins 118 and 119 into their normalpositions.- The abutment faces 131 on the lever arms 1.16, 117 drive thebody 113 and the blade 101 on the same by means of the faces 129.

The thickness of the line to be trimmed is determined by the distancebetween the edges of the blades 101 and 100. This distance depends onthe position of the face 98, because this limits the movement of theblade 101 by means of the lever arm 11%. The face 98 is on the bodyforming the mold and can be so'made on each individual mold that, whenthe mold in question approaches the blades, the blade is positionedcorresponding to the width of the mold. The blades can be adjustedexactly, without departing from the scope of the invention, solely bythe stops or abutments 133 (Figs. 7, 9 and'10), in which event the stop98 becomes superfiuous. This is without significance for the essence ofthe invention. Namely, according to the invention the blades 100 and 101are adjusted for a definite line-body or width of mold by stops orabutments which are arranged on the mold itself and which cause theblades to be adjusted whenever the mold is changed. The specialadvantage of the stops 133 is that the spring 134 does not require theextensibility requisite for the entire movementof the blade carrier 113and therefore can be selected very powerful in spite of the limitedspace, so that the movable blade 101 is held securely in its operativeposition. But it is necessary, however, that the stops or abutments 133be approximately adapted to the width of the molds and bring about arough adjustment of the bladeltll.

As follows from the above, the distance between-the blades isadjustedeach time, corresponding to the width of the mold used and thereforechanges automatically when a different mold is used. To change the moldand to make the requisite fresh adjustment of the blades 16?.111'88 onlyone single ma- 'nipulation, name y a movement of the lever manifoldways. The mold-wheels, for ex-- 73. The segment 71 on this lever, whichoperates the other members for adjusting the mold and blades, maybeconnected with an existing handle, a; 9. one serving in machineshavingseveral ma 'azines for changing the latter, so that-w en themagazine is changed a change of mold occurs automatically.

The above described illustrative embodiment of the invention ean'bemodified in ample, may contain an optional number of like or differentmolds. Then when one of these molds arrives after use into the ej'cction position, every other-mold in the wheel can be brought into thecasting position by a partial rotation of co'rres onding amount anddirection. These artial rotations can be brought about rea ily by meansof reversible toothed wheel gearing of suitable ratio of transmission.The arrangement of.

a largenumber of reversible gears is well known generally in machineconstuction, g. in motor-cars. Also it is not necessary for the partialrotation serving forplacing a mold into the casting position to takeplace at the beginning of the entire casting operation. but otherwise itmust take place between the ejection of one line and the casting of thenext.
